Markets Review
U.S. small/mid cap equities delivered moderate performance in the fourth quarter of 2025. The quarter began with a continuation of the post-Liberation Day risk-on market environment before a brief November sell-off due to growing concerns about a potential artificial intelligence capex bubble, valuations, and the market re-pricing the probability of December Fed rate cuts. The Russell 2500 ultimately rallied to a new all-time high in mid-December and finished the quarter +2.22% and +11.91% for the full year. The index posted a strong return despite geopolitical uncertainty and tariff concerns as optimism around AI-driven productivity and resilient consumer spending helped sustain gains. The rally occurred with a generally favorable macroeconomic backdrop, including a 25 basis point rate cut by the Federal Reserve in December. U.S. GDP growth remained strong at 4.3% in Q3, supported by stronger than anticipated consumer spending and positive trade developments. Inflation edged higher to 3.1%, driven in part by higher energy costs and tariff passthroughs, but remained within a manageable range for businesses and consumers. Small/mid caps benefited from attractive relative valuations, broadening of market breadth, earnings recovery and a rotation away from mega cap stocks.
Stylistically, value stocks outperformed their growth counterparts during the quarter as the Russell 2500 Value Index returned 3.15% compared to the 0.33% return of the Russell 2500 Growth index. This continues the 2024 trend where growth significantly outperformed value.
From a factor perspective, lower quality companies outperformed higher quality companies during the quarter. Factors that had the strongest payoffs were high bankruptcy risk, low sales growth, low enterprise value to EBITDA, high beta, low price to earnings, negative free cash flow, and non-earners.
At the sector level, there was mixed performance between cyclical and defensive stocks. The best performing sectors were Health Care (+12.37%), Communication Services (+3.51%), and Materials (+3.38%), while the worst performing sectors were Consumer Staples (-7.43%), Consumer Discretionary (-2.78%), and Utilities (-1.48%).

Performance Review
For the fourth quarter of 2025, the Aristotle Small/Mid Cap Equity Composite generated a total return of 2.46% net of fees (2.59% gross of fees), outperforming the 2.22% total return of the Russell 2500 Index. The largest contributor to relative performance was security selection in Industrials and Information Technology coupled with underweight allocations to Consumer Discretionary and Real Estate. Security selection in Health Care (a combination of stocks we owned coupled with not owning biotechnology) and Consumer Discretionary coupled with overweight allocations to Consumer Staples and Energy detracted from performance.

CONTRIBUTORS
Ciena (CIEN), is an optical networking equipment manufacturer for telecommunications and web scale network operators. The stock was bolstered due to strong earnings results and optimistic forward guidance driven by AI-related demand and technological innovation including dominating the market share for scale across data center projects in 2026. We believe the company is well-positioned to benefit from strong demand for bandwidth given its differentiated product portfolio and history of technological innovation, which should lead to strong operating results and shareholder value creation.
MACOM Technology Solutions (MTSI), is a designer and manufacturer of high-performance semiconductor products. The stock benefitted from strong quarterly results beating analyst expectations. We maintain our position, as we believe the company’s meaningful exposure to growing demand from Data Center and 5G end market applications along with the integration of recent acquisitions and domestic manufacturing footprint should continue to drive shareholder value.
DETRACTORS
Itron (ITRI), is a global manufacturer and distributor of electric, water and gas meters and advanced meter systems. Shares sold off following the 3Q25 earnings print due to slower than anticipated regulatory approvals; however, we believe that these challenges will be short-lived and expect an acceleration in 2026. We maintain a position, as we believe the company remains well-positioned to benefit from power grid modernization efforts, which should continue to drive demand for the company’s smart metering and grid monitoring solutions.
Encompass Health (EHC), is a provider of post-acute specialized rehabilitative inpatient treatment healthcare services. The company delivered mixed Q3 results, however management raised forward guidance and continues to execute on their plan to strategically add capacity with the anticipated roll out of small format hospitals in 2027. We maintain our position, as we believe favorable demographics trends and a stable reimbursement outlook will provide attractive growth potential for the company.

BUYS/ACQUISITIONS
Atlantic Union Bankshares (AUB), is a VA-based, bank holding company serving the VA, DC, MD and NC markets. Concerns about the potential negative impact to banking customers in their served markets from DOGE-related cuts created an opportunity to build a position in the company. Given the company’s diversified customer base, growing market share from increased scale following a meaningful market expanding acquisition and solid balance sheet, we believe that the DOGE-related overhang presents an attractive opportunity to own a high-quality bank led by a strong management team that should drive capital appreciation for shareholders.
BJ’s Wholesale Club Holdings (BJ), is a MA-based retailer operating membership warehouse clubs that sell a wide variety of goods from groceries and housewares to electronics, appliances and jewelry. With the company benefitting from better than expected performance from recently opened stores that highlights their strong fundamental execution and a pipeline of new stores in development, we believe that management should be able to continue these efforts to grow shareholder value over the next several years.
IDACORP (IDA), is an ID-based, vertically integrated electric utility that provides service to customers in southern Idaho and eastern Oregon. Strong industrial load growth and robust population migration into its service territory, combined with critical regional transmission opportunities, underpin the company’s robust five-year capital plan and double-digit rate base growth outlook. We believe this expansion, facilitated by a constructive regulatory environment and a proven management team, should drive consistent earnings growth and long-term capital appreciation for shareholders.
Novanta (NOVT), is a MA-based supplier of advanced photonics, vision, and precision motion technologies that power high‑performance medical, life science, and industrial automation applications. Supply chain disruption, tariffs, and soft end-markets have weighed on gross margin expansion over the last two years. With these headwinds abating and a strong pipeline of new design wins, the company is expected to return to solid, above average revenue and earnings growth driven, in part, by higher-margin new products, site consolidation, and lean initiatives.
Perella Weinberg Partners (PWP), is a boutique investment bank that has been investing in incremental deal capacity through strategic hires of experienced investment bankers. An expected upturn in M&A activity over the next several years following a period of below average activity should allow the company to operationally leverage the investments they’ve been making during the downturn. Deal pipelines remain near all-time highs, activity is increasing, and the market is pricing in future modest interest rate cuts, which increases confidence that sustained M&A volume recovery is growing. This environment should allow the company to generate shareholder value over the coming years.
UGI Corporation (UGI), is a PA-based energy infrastructure company operating regulated natural gas utilities, midstream and marketing assets, AmeriGas retail propane distribution, and international LPG services. Under the leadership of a new, highly experienced and highly respected CEO, UGI is implementing an operational reset at AmeriGas while executing a strategic pivot toward its stable utility footprint and underappreciated Midstream assets that we believe are well positioned to capitalize on regional demand. This management-led transformation, coupled with non-core divestitures and an improving balance sheet, should drive greater predictability and support a more durable long-term earnings growth profile.
SELLS/LIQUIDATIONS
Carlisle Companies (CSL), is a diversified industrial manufacturer of nonresidential roofing materials and industrial connectivity products. The position appreciated during the holding period and was liquidated to redeploy capital to new opportunities for future upside potential.
Chart Industries (GTLS), is a manufacturer of engineering equipment for the industrial gas, energy, and biomedical industries. The company is being acquired by Baker Hughes (BKR).
eHealth (EHTH), is a provider of Internet-based health insurance agency services for individuals, families, and small businesses operating through Medicare, employer and individual business segments. The position was liquidated due to deteriorated fundamental performance and an uncertain strategic outlook.
NorthWestern (NWE), generates, transmits, and distributes regulated electricity and natural gas to customers across Montana, South Dakota, and Nebraska. The position was sold following its all-stock merger announcement with Black Hills (BKH). We decided to step aside while we evaluate the combined entity’s integration timeline and future regulatory considerations from the sidelines.
Nu Skin Enterprises (NUS), is a developer and distributor of beauty and wellness solutions. The position was liquidated due to deteriorated fundamental performance and an ongoing strategic transformation with an uncertain fundamental outlook.
Patterson-UTI Energy (PTEN), is an oilfield services company focused on drilling and pressure pumping solutions for both major oil companies and independent operators. The position was liquidated due to the energy market outlook weakening thus deteriorating fundamental performance.
TreeHouse Foods (THS), is a manufacturer and distributor of private label packaged foods and beverages in North America. Its product portfolio includes snacking, beverages, and meal preparation products, available in shelf stable, refrigerated, frozen, and fresh formats. The position was liquidated ahead of its pending acquisition by a private equity consortium.
Westinghouse Air Brake Technologies (WAB), is provider of equipment, systems, and value-added services for the rail industry. This was a long-time position that successfully grew from the small cap space to a large cap company beyond the strategy’s intended investment universe. We redeployed the capital to new positions that we believe present the opportunity for future upside potential.
Outlook
We remain optimistic about the long-term potential for the small/mid-cap segment of the U.S. market. Valuations remain compelling relative to large caps, with the Russell 2500 Index trading near the lower end of its historical range. Potential tailwinds, including deregulation, lower corporate tax rates, increased M&A activity, continued reshoring of U.S. manufacturing, and infrastructure-related spending, could provide additional support for small/mid-cap stocks. Volatility remains elevated over concerns around inflationary risks, geopolitical tensions, and potential U.S. economic and labor weakness.
Positioning
Our current positioning is a function of our bottom-up security selection process and our ability to identify what we view as attractive investment candidates, regardless of economic sector definitions. Overweights in Information Technology and Materials are mostly a function of our underlying company specific views rather than any top-down predictions for each sector. Conversely, we continue to be underweight in Consumer Discretionary, as we have been unable to identify what we consider to be compelling long-term opportunities that fit our discipline given the rising risk profiles of many retail businesses and a potential deceleration in goods spending following a period of strength. We are also underweight in Financials as the sector has experienced strong returns, leading us to harvest gains and redeploy the proceeds to what we consider to be more attractive reward to risk opportunities. Given our focus on long-term business fundamentals, our patient investment approach and low portfolio turnover, the strategy’s sector positioning generally does not change significantly from quarter to quarter. However, we may take advantage of periods of volatility by adding selectively to certain companies when appropriate.

All investments carry a certain degree of risk, including the possible loss of principal. Investments are also subject to political, market, currency and regulatory risks or economic developments. International investments involve special risks that may in particular cause a loss in principal, including currency fluctuation, lower liquidity, different accounting methods and economic and political systems, and higher transaction costs. These risks typically are greater in emerging markets. While Large-capitalization companies may have more stable prices than smaller, less established companies, they are still subject to equity securities risk. In addition, large-capitalization equity security prices may not rise as much as prices of equity securities of small-capitalization companies. Securities of small- and medium-sized companies tend to have a shorter history of operations, be more volatile and less liquid.
